El día que los crayones renunciaron

Many readers highly praise the book for its exceptional humor and creativity, finding it genuinely funny for both children and adults. The unique concept of crayons expressing their grievances through letters is consistently highlighted as imaginative and engaging. Reviewers commend the illustrations, often described as fantastic, brilliant, and adorable, with a charming childlike quality and clever details that enhance the text. The distinct personalities of each crayon are well-developed and relatable, contributing to the book's charm. Furthermore, the book is lauded for encouraging creativity and imaginative thinking, with some noting its potential to inspire children to speak up for themselves and consider the needs of others. Its epistolary format is also recognized as a clever and engaging storytelling device.

Despite its popularity, some reviewers express significant reservations about the book's originality, pointing to a strong resemblance to an older title, "The Crayon Box That Talked," which raises concerns about its innovative merit. Critics also suggest that while humorous, the book may lack a deeper, more meaningful message or a satisfying resolution compared to other children's literature. Some jokes are perceived as too snarky or complex for younger children, potentially aiming more for adult laughs. Specific criticisms include the storyline involving a "naked" crayon, which some found strained or inappropriate for encouraging certain giggles in young children. Additionally, the representation of skin tones through the crayons is a point of contention for some, who note the absence of a distinct brown crayon and the equating of peach and pink with flesh tones without broader diversity. A practical concern raised is the difficulty for young readers to independently read the varied, handwritten fonts used for the crayon letters.

Overall, the book is widely regarded as a cute, fun, and engaging read, often described as a "winner" that captivates its audience. While it garners praise for its humor and artistic merit, potential readers should be aware of the mixed opinions regarding its originality and the depth of its underlying messages. This book is particularly recommended for children aged four and up, as well as for adults who appreciate clever wordplay and charming illustrations in children's literature. It makes an excellent choice for family read-alouds, where the humor can be shared across generations, and for encouraging imaginative play and discussions about different perspectives.
